Q. No.A string of mass \(2.5~\text{kg}\) is under a tension of \(200~\text N.\) The length of the stretched string is \(20.0~\text m.\) If the transverse jerk is struck at one end of the string, the disturbance will reach the other end in:
| 1. | \(1\) second |
| 2. | \(0.5\) second |
| 3. | \(2\) seconds |
| 4. | The data given is insufficient |

The transverse displacement of a string (clamped at its both ends) is given by \(y (x,t) = 0.06 ~\sin (2πx/3) ~\cos (120πt)\). All the points on the string between two consecutive nodes vibrate with
(a) same frequency
(b) same phase
(c) same energy
(d) different amplitude.
Choose the correct option:
(a) same frequency
(b) same phase
(c) same energy
(d) different amplitude.
Choose the correct option:
| 1. | (a), (c) | 2. | (a), (b), (d) |
| 3. | (b), (d) | 4. | (c), (d) |
